Abstract

A multi-layer polyethylene film especially suitable for garbage and refuse bags, comprising a first layer of at least 75 wt. % high pressure-low density polyethylene (HPLPDE), and at least a second layer of HPLDPE and low pressure-low density polyethylene (LPLDPE), in which the LPLDPE is less than about 25 wt. % of the LPLDPE plus HPLDPE total weight.
